Fine-tuning wav2vec2 for speaker recognition (2109.15053v2)

Abstract: This paper explores applying the wav2vec2 framework to speaker recognition instead of speech recognition. We study the effectiveness of the pre-trained weights on the speaker recognition task, and how to pool the wav2vec2 output sequence into a fixed-length speaker embedding. To adapt the framework to speaker recognition, we propose a single-utterance classification variant with CE or AAM softmax loss, and an utterance-pair classification variant with BCE loss. Our best performing variant, w2v2-aam, achieves a 1.88% EER on the extended voxceleb1 test set compared to 1.69% EER with an ECAPA-TDNN baseline. Code is available at https://github.com/nikvaessen/w2v2-speaker.

• The document provides comprehensive guidelines for authors submitting manuscripts to ICASSP 2021, covering formatting, typography, illustrations, and references to ensure uniformity and quality.
• Key structural rules mandate a two-column format with specified margins and dimensions, recommending Times-Roman font for consistency.
• The guidelines detail standards for section headings, figures positioning, and proper referencing, requiring citations to be listed either alphabetically or by order of appearance, potentially on a dedicated extra page.

Overview of ICASSP 2021 Author Guidelines

This document outlines the comprehensive guidelines for authors submitting manuscripts to the ICASSP 2021 proceedings. It is a highly structured manual intended to ensure uniformity and professional quality in conference materials, addressing various aspects of manuscript preparation—ranging from formatting and typography to the inclusion of illustrations and pagination. This standardization is pivotal, given the technical depth and breadth typically embodied in the ICASSP submissions, which span numerous topics in signal processing.

Key Structural Guidelines

The document carefully prescribes the spatial layout of submitted papers. Authors are instructed to maintain all printed matter within a meticulously defined print area, ensuring neither text nor illustrations exceed specified margins. Adherence to a two-column format is mandatory, with explicit dimensions provided for both column width and inter-column spacing. Such precise requirements serve the dual purpose of maximizing efficient use of space and enhancing readability. Use of the Times-Roman font is strongly recommended to maintain consistency across printed and digital mediums.

Section Headings and Type-Style

The paper articulates clear directives for the hierarchical arrangement of section headings. Major headings must be uppercase and centered, while subheadings are to be formatted in bold and aligned with the left margin. This structured approach extends to sub-subheadings, though their use is discouraged unless imperative. The consistent application of such typographical norms aids in guiding readers through complex discussions, ensuring logical flow and clarity.

Figures and Illustrations

Positioning of figures receives special attention, with an emphasis on integrating them at the top of columns to optimize document structure. The guidelines acknowledge the diversity of methods available in LaTeX for including images but recommend precedents to ensure compatibility. Color is permissible yet cautioned, considering potential printing constraints. This careful curation of visual aids is instrumental in effectively conveying empirical data, crucial in fields reliant on quantitative analysis.

References and Citations

Proper attribution is a central tenet, with detailed expectations laid out for the treatment of prior work and references. Authors are tasked with situating their contributions within the existing body of knowledge, delineating both innovation and distinction. The references must be listed either alphabetically or in the order of citation, with a reserved additional page allowed solely for this purpose. This methodical referencing protocol ensures academic rigor and fosters an understanding of the work’s lineage.

Theoretical and Practical Implications

While the guidelines presented focus heavily on the procedural aspects of manuscript preparation, the implications of such meticulous curation extend into both theoretical and practical domains. The standardization across all submissions facilitates equitable assessment and peer review processes, allowing evaluators to concentrate on content rather than presentation disparities. By enforcing these guidelines, the conference can efficiently handle diverse contributions, ultimately promoting robust scholarly discourse during proceedings.

In conclusion, the ICASSP 2021 author guidelines provide an exhaustive framework for manuscript preparation, reinforcing consistency and quality. These structural, typographic, and content-based directives not only streamline the submission process but also uphold the integrity and scholarly caliber expected at an international conference of this magnitude. As digital and printed mediums evolve, adherence to such precise standards remains integral, ensuring resilient academic communication. Future developments in AI and document processing may further refine these guidelines, aligning traditional formats with emerging digital paradigms.
